Abstract
Provided is a method for sensing ice-making water in a refrigerator. The method includes activating a pump to move water from a water tank to an ice-making chamber; comparing a temperature of the ice-making chamber with an ice-making reference temperature set; when the temperature of the ice-making chamber is equal to the ice-making reference temperature, calculating an ice-making consumption time until the ice-making reference temperature after the activating of the pump; comparing the ice-making consumption time with an ice-making reference time set; and when the ice-making consumption time is smaller than the ice-making reference time, determining that there is no water in the water tank.
Claims10
A method for sensing ice-making water in a refrigerator, the method comprising:
- activating a pump to move water from a water tank to an ice-making chamber;
- comparing a temperature (T1) of the ice-making chamber with an ice-making reference temperature (T) set;
- when the temperature (T1) of the ice-making chamber is equal to the ice-making reference temperature (T), calculating an ice-making consumption time (Sn) until the ice-making reference temperature (T) after the activating of the pump;
- comparing the ice-making consumption time (Sn) with an ice-making reference time (S) set;
- and
- when the ice-making consumption time (Sn) is smaller than the ice-making reference time (S), determining that there is no water in the water tank.
